Similar prognostic ability for each of the three methods to quantify proteinuria for characterizing a >50% decline in GFR or need for RRT based on clinically meaningful cutoffs of UP/C (Kaplan–Meier, dashed lines and Generalized Gamma, solid lines). Left panel: UP/C categorized as <0.2, 0.2–2.0, and >2.0; middle panel: ACR categorized as <56, 56 to <1333, and >1333; right panel: Unon-alb/cr categorized as <118, 118 to <715, and >715. n=751. ACR, urine albumin-to-creatinine ratio; Unon-alb/cr, urine nonalbumin-to-creatinine ratio; UP/C, urine protein-to-creatinine ratio.
